Lightroom becomes unresponsive when scrolling/navigating thumbnails in any view.

[Chunk887]

Version: 5.2 20220128-1049-86119e0

CPU: I7-8700K

GPU: GeForce GTX 1080TI

OS: Windows 10 Pro 10.0.19043

For many months now (it may be over a year at this point) I've had problems running the Windows application for lightroom CC. At one point it worked excellently, I was able to rapidly workthrough fresh imports, now it's impossible to get through any bulk amount of photos due to all the freezes.

When scrolling through photos in any of the thumbnail views (Square, Photo, or Filmstrip) the application becomes unresponsive for 30 seconds to a minute and one of my CPU cores will be at 100% for the duration. Basically any action that will require the application to display additional/different thumbnails results in a temporarily unresponsive application, this includes resizing the window itself in any multi-photo view.

I have no issues while actually editing photos, provided I don't accidentially navigate the filmstrip while doing so.

I've tried turning on/off the setting for storing a copy of smart previews, no difference.

I've tried many of the suggested troubleshooting related to performance issues for lightroom, but what adds to the frustration is many of these articles (by Adobe and elsewhere) are targeted to Lightroom Classic, not the cloud application, and many of the steps are not applicable or menu options do not exist.

I have tried using the application with GPU acceleration on and off, there is no difference.

The application works fine on my relatively lower powered laptop with no problems (other than lower performance which can be attributed to it being a less powerful machine)

Do you see the same behavior in 5.4 (released a week ago)?

[Chunk887]

Yes, I noticed there was an update right after sending this, and applied it.

Same issue remains.

The engineer relayed to me to thank you for the video. It was helpful. 

Does the performance change depending upon whether the filter bar is populated or not? We noticed that the workd "Public" appears in the filter bar. If the filter bar is clear, what happens?

[Chunk887]

It presents identically, the  filter was only for the purposes of posting here.

[Rikk Flohr: Photography]

Thanks for the update. 

The engineer is asking if you can record a second screen video with no filter. He asks that you scroll down to the middle and just wait until for the grid to populate. 

Please have the Task Manager in the lower right and visible as you did in the previous video. That was very helpful. 

Thanks!

[Chunk887]

Rikk I can do this but is there somewhere else I can have this correspondence or share the video.

If I disable the filter there will be photos visible I'd rather not have shared here. Nothing explicit just personal.

[Rikk Flohr: Photography]

When you have the video ready for delivery. Drop a note in the forum here and I will send you instructions. 

[Chunk887]

Let me know where to send it, I have it prepped.

[Rikk Flohr: Photography]

You should have a shared folder invitation in your email. 

[Chunk887]

I've uploaded the video.

[Chunk887]

Sorry disregard my other post, the folder is read-only.

[Rikk Flohr: Photography]

Refresh your browser and try it again.

Good to go now!

[Chunk887]

Any updates on this?

[Chunk887]

Following up again. I'd love to be able to use the subscription I've been paying for.

[Chunk887]

Please help.

I see similar behavior on my backup laptop. However, I am 99% sure the problem is self inflicted in my case.

On my backup laptop, I have a 256GB SSD, with only 10GB available, and cache size in Lr set to the default.

I know the system struggles working in such a small space.

Note: I have 30K images and I believe 600GB of space used the cloud.

You might want to eliminate this variable.

[Chunk887]

There isn't any space constraints, that's been something I've been keeping an eye one.

I have noticed though that my cache is showing as having no size or 0kb, despite me allowing it to use space. It doesn't grow at all where as on my laptop it has a fair amount of size.

I don't know if this is expected behaviour as I have lightroom keeping full size images stored on another disk on the system.

[Timothy.Spear]

My cache is also 0kb reported and basically when looking at the disk is also empty on my desktop where I have all originals on a secondary disk.

Based on your posted video above. I was watching disk 0; which is an HDD. This was jumping up to a couple percent at most. On my desktop where I have the originals on the secondary HDD (technically a mirror set) I am

seeing the HDD go as high as 60% when I scroll through the images.

I am making the assumption you have the SSD for drive C. And are using the two HDD for data storage. (Similar to my setup).

On the off chance this is a Windows/HW issue with the HDD (this test will NOT find all potential problem points). I would disable the local storage of originals (this will cause it to re-download everything when you re-enable). And just use the cache on drive C. And see how the system performs. Now if you have a lot of images, the drive C cache will only keep up with so much. But see if the performance is better. If yes, then you have an issue accessing the HDD.

Yeah I'm gonna have to pass on that, recently redownloaded the entire library, through the process of this thread, not something I'm looking to revisit so soon.

[Chunk887]

I gave this a stab still no improvement.

[Timothy.Spear]

The best bet to me, would be to use a performance monitor and start looking for system bottle necks.

Good luck,

Tim

[Chunk887]

I've tried this, provided video to Adobe with it as well.

[Chunk887]

Coming up on a year and I still have this issue. Just updated to latest version.

[Timothy.Spear]

What performance monitoring have you done to find the potential bottleneck?
